DETAILED DESCRIPTION

Certain exemplary embodiments are described in higher detail below with reference to the accompanying drawings.

In the following description, like drawing reference numerals are used for the like elements, even in different drawings. The matters defined in the description, such as detailed construction and elements, are provided to assist in a comprehensive understanding of exemplary embodiments. However, exemplary embodiments can be practiced without those specifically defined matters. Also, well-known functions or constructions are not described in detail since they would obscure the application with unnecessary detail.

FIG. 1 is a block diagram illustrating the configuration of a home network system according to an exemplary embodiment.

Referring to FIG. 1, the home network system 1000 comprises a broadcast receiver 100 and a control device 200. The broadcast receiver 100 provides a user with an image or video/audio information, and may be embodied as a digital TV, STB, PC, notebook computer, personal media player (PMP), and so on. Specifically, the broadcast receiver 100 may include a display unit 110, a storage unit 120, a communication interface unit 130, a determination unit 140, and a control unit 150.

The display unit 110 may display information provided by the broadcast receiver 100. The display unit 110 may be an apparatus which is capable of receiving and outputting data such as a touch pad device, or may be an image display apparatus such as a liquid crystal display (LCD), plasma display panel (PDP) and cathode ray-tube (CRT). Furthermore, the control device 200 may receive a service screen provided by the broadcast receiver 100.

In addition, the display unit 110 of the broadcast receiver 100 may display a menu for selecting a service by a user. Specifically, if the determination unit 140 which will be explained later determines that a menu is displayed on the broadcast receiver 100, a menu for selecting a service by a user may be displayed. On the other hand, if the determination unit 140 determines that a menu is displayed only on the control device 200, the display unit 110 of the broadcast receiver 100 may not display a menu.

Meanwhile, if the broadcast receiver 100 is an apparatus such as a digital TV, the display unit 110 may be an internal component of the digital TV, and if the broadcast receiver 110 is a set-top box, the display unit 110 may be an external component or apparatus (such as a monitor or a TV connected to the set-top box).

The storage unit 120 may store contents corresponding to various services supported by the broadcast receiver 100. In addition, the storage unit 120 may store a plurality of user interface windows corresponding to an operation mode of the broadcast receiver 100. As such, the storage unit 120 may be embodied as a storage medium inside the broadcast receiver 100, an external storage medium such as a removable disk including a USB memory, a storage medium connected to a separate host, or a web server connected to the broadcast receiver 100 via a network.

The communication interface unit 130 transmits menu information. Specifically, the communication interface unit 130 may form a link to the communication interface unit 210 of the control device 200 and transmit menu information to the communication interface unit 130 through bi-directional wireless communication. In addition, the communication interface unit 130 may transmit a user interface window corresponding to an operation mode of the broadcast receiver 100 according to a request from the control device 200.

In addition, the communication interface unit 130 may receive a control command of a user from the control device 200. Meanwhile, such transmission of menu information may be performed in accordance with a request from the control device 200, or may be performed without any particular request.

Herein, the bi-directional communication may include all of the existing communication technologies such as Bluetooth (BT), Radio Frequency (RF), Wireless Fidelity (Wi-Fi), High Definition Multimedia Interface—Consumer Electronic Control (HDMI-CEC), and Wireless HDMI-CEC and all of the future bi-directional wireless communication technologies.

The menu information is information to help a user select a service of a broadcast receiver and may include information regarding channel, current volume, play time, remaining play time, current time, Electronic Program Guide (EPG), an operation mode of a broadcast receiver, and a current screen displayed on a broadcast receiver.

The communication interface unit 130 may receive the menu information and the user interface window from an external server (not shown). Specifically, the communication interface unit 130 may receive the menu information and the user interface window from an external server which provides information such as EPG information or an external server of a manufacturer of ‘a control device or a broadcast receiver’.

The determination unit 140 determines an apparatus in which to display a menu for controlling the broadcast receiver 100. Specifically, the determination unit 140 may receive information regarding a control mode determined by the control device 200 and determine in which apparatus to display the menu. For example, if a control mode determined by the control device 200 is a first control mode, the determination unit 140 may determine that the menu is to be displayed on the broadcast receiver 100, and if a control mode determined by the control device 200 is a second control mode, the determination unit 140 may determine that the menu is to be displayed on a control device.

The determination unit 140 may also identify a grip direction of a user with respect to the control device 200 using a photographing sensor and determine an apparatus in which to display a menu according to the identified grip direction. For example, if the identified grip direction of a user with respect to the control device is a vertical direction, the determination unit 140 may determine that a menu is to be displayed on the broadcast receiver 100, which is the first control mode, and if the identified grip direction of a user with respect to the control device is a horizontal direction, the determination unit 140 may determine that a menu is to be displayed on the control device 200, which is the second control mode.

The control unit 150 controls each component of the broadcast receiver 100. Specifically, if the determination unit 140 determines that a menu is to be displayed on the broadcast receiver 100, which is the first control mode, the control unit 150 may control the display unit 110 to display the menu on the broadcast receiver 100. Alternatively, if the determination unit 140 determines that a menu is to be displayed on the control device 200, which is the second control mode, the control unit 150 may control the display unit 110 not to display the menu on the broadcast receiver 100. Meanwhile, menu information may be transmitted to the control device 200 only when a control mode of the control device 200 is the second control mode.

In addition, the control unit 150 may control a service operation or a service state of the broadcast receiver 100 according to a received control command and provides a service accordingly. For example, if the broadcast receiver 100 receives a control command of ‘TV channel up’ from the control device 200, the control unit 150 may provide a command to the TV in which a TV channel is changed. If the control device 200 requests screen information displayed on the broadcast receiver 100, the control unit 150 may control the communication interface unit 130 to transmit the screen information being displayed on the display unit 110 of the broadcast receiver 100 to the control device 200. Accordingly, a user may view the same screen information displayed on the broadcast receiver 100 on the control device 200.

The control device 200 controls the broadcast receiver 100 using bi-directional wireless communication and may be embodied as a remote controller, a mobile phone, an MP3 player, a navigator, or a digital photo frame. Specifically, the control device 200 may include a communication interface unit 210, a storage unit 220, a user interface unit 230, a determination unit 240, and a control unit 250.

The communication interface unit 210 requests the broadcast receiver 100 to send menu information. Specifically, the communication interface unit 210 may form a link to perform bi-directional wireless communication with the communication interface unit 130 of the broadcast receiver 100, request menu information to be displayed on the user interface unit 230 which will be explained later through the formed link, and receive the menu information. Meanwhile, the communication interface unit 210 may request the broadcast receiver 100 to send menu information only when a control mode of the control device 200 determined by the determination unit 240 which will be explained later is in the second control mode. When menu information is requested, information regarding a control mode determined by the determination unit 240 which will be explained later may be transmitted to the broadcast receiver 100.

Such a request for menu information may be made to an external server (not shown). Specifically, the communication interface unit 210 may request a broadcast receiver 100 which is communicable with an external server (not shown) or an external server itself to send menu information and receive the menu information accordingly.

In addition, the communication interface unit 210 may transmit a control command received from the user interface unit 230 which will be explained later to the broadcast receiver 100.

The storage unit 220 may store broadcast information received through the communication interface unit 210 and a user interface window corresponding to an operation mode of the broadcast receiver 100. The storage unit 220 may be embodied as a storage medium in the control device 200 or as an external storage medium such as a removable disk including a USB memory and a web server via a network. A plurality of user interface windows stored in the storage unit 220 may be provided from the broadcast receiver 100.

The user interface unit 230 displays a user interface window to receive a control command and receives a control command for the broadcast receiver 100. Specifically, the user interface unit 230 has a plurality of function keys through which a user may set or select various functions supported by the broadcast receiver 100 and display a plurality of user interface windows for controlling the broadcast receiver 100. The user interface unit 230 may be embodied as an apparatus which is capable of inputting and outputting data simultaneously such as a touch pad or as an apparatus which combines a key pad with a display apparatus.

In addition, the user interface unit 230 may display a user interface window according to an operation mode of the broadcast receiver 100. Specifically, if the broadcast receiver 100 is displaying a TV broadcast, the user interface unit 230 may include various modes such as a TV control mode, a VTR control mode, and a search control mode according to the operation of the broadcast receiver 100. That is, if a user watches a TV using a broadcast receiver, a user interface window customized to control the TV may be displayed on the user interface unit 230. Alternatively, if a user watches a DVD using a broadcast receiver, a user interface window customized to watch the DVD may be displayed on the interface unit 230.

In addition, the user interface unit 230 may display received menu information on a user interface window. Specifically, the user interface unit 230 may display menu information received through the communication interface unit 210 along with a user interface window according to the above-mentioned operation mode. Such a user interface window will be explained with reference to FIGS. 4 to 6.

The determination unit 240 determines a control mode of the control device 200. Specifically, the determination unit 240 may control the control unit 250 to control the user interface unit 230 to display a user interface window according to the control mode of the control device 200. The determination unit 240 may further determine a location or positioning of the menu on the user interface window according to the control mode selected by a user through the displayed user interface window. Herein, the control mode may include a first control mode where a menu having only an area for receiving a control command regarding a broadcast receiver is displayed on a user interface window (that is, a mode where the broadcast receiver displays a menu) and a second control mode where a menu showing menu information is displayed on a user interface window (that is, a mode where a control device displays a menu).

Additionally, the determination unit 240 may also identify a grip direction of a user with respect to the control device 200, or how a user holds the control device 200, using a gyro sensor and determine a control mode corresponding to the grip direction of the user. For example, if the grip direction of a user is in a vertical direction with respect to the user, or in other words if the user holds the control device 200 in a vertical direction, the determination unit 240 may determine a control mode as the first control mode in which only an area for receiving a control command regarding a broadcast receiver 100 is displayed on a user interface window. If the grip direction of a user is in a horizontal direction with respect to the user, the determination unit 240 may determine a control mode as the second control mode in which received menu information is displayed on a user interface window.

The control unit 250 controls each component of the control device 200. Specifically, if the determination unit 240 determines a control mode as the first control mode, the control unit 250 may control the user interface unit 230 to display a user interface window according to the operation mode of the broadcast receiver 100. If the determination unit 240 determines a control mode as the second control mode, the control unit 250 may control the user interface unit 230 to display received menu information along with a user interface window according to the operation mode of the broadcast receiver 100.

In addition, if a control command is input from a user through the displayed user interface window, the control unit 250 may control the communication interface unit 110 to transmit the input control command to the broadcast receiver 100.

Meanwhile, if the control device 200 is disposed in a horizontal direction with respect to a user, the control unit 250 may control the control device 200 to display a screen being displayed on the broadcast receiver 100 on a user interface. Specifically, if it is determined that the control device 200 is disposed in a horizontal direction with respect to a user, the control unit 250 may request the broadcast receiver 100 to transmit a screen currently being displayed on the broadcast receiver 100 to the control device 200 and control the user interface unit 230 to display the screen received from the broadcast receiver 100.

Therefore, the control device according to an exemplary embodiment displays a location where a menu is displayed on the menu or on the control device according to a user's preference and circumstance, thereby improving user convenience.

In the above description regarding FIG. 1, the control device 200 controls only one broadcast receiver 100, but the control device 200 may control a plurality of broadcast receivers 100.

FIG. 2 is a view illustrating an example of connection of a home network system 1000 according to an exemplary embodiment.

Referring to FIG. 2, the home network system 1000 includes the broadcast receiver 100 and the control device 200. The broadcast receiver 100 and the control device 200 are connected by performing bi-directional communication. Accordingly, the broadcast receiver 100 may transmit menu information to the control device 200 and also receive a user's control command using bi-directional communication.

Meanwhile, the broadcast receiver 100 may display a menu 111 on the display unit 110 in accordance with a user's control command. Specifically, if the control device 200 operates in the first control mode as described above, menu information is displayed on the broadcast receiver 100.

If a user changes a control mode using the area 232 for selecting a control mode of the control device 200, the control device 200 may display menu information received from the broadcast receiver 100 as illustrated in FIGS. 4 and 5. In this case, the broadcast receiver 100 may stop displaying the menu.

Specifically, the user interface unit 230 of the control device 200 may display a user interface window including a first area 231 for receiving a user's control command and a second area 232 for receiving a control mode.

The first area 231 is an area for receiving a user's control command and may display a user interface window as illustrated in FIGS. 3 to 5 according to an operation mode of the broadcast receiver 100 and a control mode of the control device 200.

Referring to FIG. 3D, if the control device 200 is operated in the first control mode and the broadcast receiver 100 is operated in a DVD watching mode, the user interface window 340 of the control device 200 displays a user interface window which is optimized to control DVD watching as a displayable user interface window.

As such, the control device 200 according to an exemplary embodiment provides a user interface window optimized to the operation mode of the broadcast receiver 100 and thus, a user may control the broadcast receiver 100 conveniently.

FIGS. 4 and 5 are views illustrating an example of a user interface window which can be displayed on a user interface unit of the control device 200 when the control device 200 is operated in the second control mode.

Referring to FIG. 4, if the control device 200 is operated in the second control mode and the broadcast receiver 100 is operated in a TV receiving mode, the user interface window 400 displays a user interface window which is optimized to control TV watching along with menu information (information regarding a channel currently selectable by a user) as a displayable user interface window.

Thus, the user may easily identify which channel is currently displayed on the broadcast receiver 100 and to which channel the current channel may be changed through the menu information displayed on the control device 200.

Referring to FIG. 5, if the control device 200 is operated in the second control mode and the broadcast receiver 100 is operated in a search mode, the user interface window 500 displays menu information, which is, a user's search result as a displayable user interface window.

Thus, a user may check the search result through the control device 200 and input a search command and perform additional search on the control device 200 directly. Therefore, user convenience may be enhanced.

Referring to FIG. 6, if the control device 200 is disposed in a horizontal direction with respect to a user, the screen being displayed on the broadcast receiver 100 is displayed on a user interface.

As such, the screen displayed on the broadcast receiver 100 may be displayed on the control device 200 according to a grip direction of the control device 200. Thus, user convenience may be enhanced.

FIG. 7 is a flowchart to explain a method for providing a service according to an exemplary embodiment.

Referring to FIG. 7, first of all, an apparatus where a menu for controlling a broadcast receiver to be displayed is determined (S710),specifically the apparatus is determined by receiving information regarding a control mode. For example, the control mode is determined by the control device 200, by identifying a grip direction of a user with respect to the control device 200 using a photographing or gyro sensor.

If it is determined that a broadcast receiver 100 is to display the menu (S720-Y), menu information is displayed (S730) on the broadcast receiver.

Alternatively, if it is determined that a control device 200 is to display the menu (S720-N), menu information is transmitted to a control device 200 (S740). Specifically, if it is determined that the menu is to be displayed on the control device 200, information which helps a user to select a desired service of a broadcast receiver 100 (such as, channel information, current volume, play time, remaining play time, current time, Electronic Program Guide (EPG), an operation mode of a broadcast receiver 100, and a current screen) is displayed on a broadcast receiver 100. Meanwhile, such transmission operation may always be provided to a control device 200 regardless of the above-mentioned control mode.

Subsequently, if a control command input from a user is received from a control device 200 (S750), a service corresponding to the received control command may be provided (S760) to the broadcast receiver 100. For example, if the broadcast receiver 100 receives a ‘TV channel up’ control command from the control device 200, a TV service or command to change a TV channel may be provided to the broadcast receiver 100. Meanwhile, if the received control command is a command to provide screen information, the screen information currently being displayed on the broadcast receiver 100 is transmitted to the control device 200 so that the screen being displayed on the broadcast receiver 100 is also displayed on the control device 200.

As such, the method for providing a service according to the exemplary embodiment allows a user to receive a service by controlling a broadcast receiver 100 through a remote mobile device, thereby enhancing user convenience. The method for providing a service illustrated in FIG. 7 may be performed not only in a broadcast receiver 100 having the configuration of FIG. 1 but also in a broadcast receiver 100 having other configurations.

FIG. 8 is a flowchart to explain a method for controlling a broadcast receiver according to another exemplary embodiment.

Referring to FIG. 8, first of all, a control mode according to an apparatus where a menu is to be displayed is determined (S810). Specifically, a user interface window for receiving at least one control mode from among a plurality of control modes is displayed and a selected control mode may be determined as a control mode of the control device 200 through the displayed user interface window. Herein, the control mode may include the first control mode in which a menu is displayed on the broadcast receiver 100 and the second control mode in which a menu is displayed on the control device 200. Meanwhile, a user's grip direction with respect to the control device 200 may be identified using a gyro sensor and the above determination may be performed according to the identified grip direction. This has been explained above with respect to the determination unit 240, so further description will not be provided.

Subsequently, menu information is requested and received from a broadcast receiver 100 (820). Specifically, menu information such as channel information, current volume, play time, remaining play time, current time, Electronic Program Guide (EPG), and an operation mode of a broadcast receiver 100 may be requested and received from a broadcast receiver 100. Such a request for menu information may be made only when a control mode is determined to be the second control mode.

The received menu information and a user interface window according to the determined control mode are displayed (S830). Specifically, if the determined control mode is the first control mode, a user interface window according to an operation mode of the broadcast receiver 100 (that is, a user interface window without menu information) is displayed, and if the determined control mode is the second control mode, menu information may also be displayed on a user interface window according to an operation mode of the broadcast receiver 100.

If a control mode regarding a broadcast receiver 100 is received using the above-mentioned user interface window from a user (S840), the input control mode is transmitted to the broadcast receiver 100 (S850).
